Instructions

  1. Step 1: Preheat oven to 150°C (300°F). Rub 1.5 kg bone-in lamb shoulder all over with 2 tsp salt, 1 tsp black pepper, 3 tbsp olive oil, and 2 tbsp lemon myrtle powder.
  2. Step 2: Place lamb in a roasting pan and roast uncovered for 3 hours, basting every hour with pan juices.
  3. Step 3: Meanwhile, combine 1/3 cup bush tomato paste, 2 tbsp honey, 4 minced garlic cloves, and 1 cup water in a small saucepan. Simmer gently for 15 minutes until thickened into a glaze.
  4. Step 4: In the last 30 minutes of roasting, brush the lamb generously with the bush tomato glaze and return to oven, allowing it to caramelize and build a rich crust.
  5. Step 5: Remove lamb from oven, rest for 15 minutes before carving and serving with remaining glaze.
